Is This Arcade Fire's New Single "Reflektor"?

And is David Bowie contributing vocals?!?

Update: The track has been removed.

Arcade Fire's new album Reflektoris out October 29 via Merge, and on Monday night (September 9 at 9 p.m.), the band will release the album's first single and Anton Corbijn-directed video, "Reflektor". Reader Drew Hufsey sent us the above audio, which he claims is a new Arcade Fire song. Is it "Reflektor"? Representatives of the band offered no comment on the song's legitimacy.

In the above audio, if you listen carefully, there's a voice that sounds an awful lot like David Bowie's. The Sun reported the rumor that Bowie joined James Murphy and Arcade Fire during the album's recording sessions. Again, the band's representatives have offered no comment on whether or not Bowie is involved.
